In Red Dwarf, Cloister is discussed briefly in The End and in more detail in Waiting for God. In that latter episode, Cat explains that "Cloister is another name for ... for God." Cloister is, of course, Lister. As the legend goes, he was frozen in time to save the life of Frankenstein, the Holy Mother. Frankenstein was Lister's pet cat, and when he refused to hand-over the cat, his punishment was to be put into stasis, or, frozen in time. Cloister is the supreme being in the cat-people's religion.
